The mode of operation of the device described above will now be explained with respect to what has not yet been clarified from the embodiments described above.

The printed product 1 supplied by the first carrier 3 of the first roof tile S1 is pushed into the intermediate stack 5 with the end 1a folded down. It
The printed products 1 on top of each of the intermediate stacks 5 are:
Suction head 11 connected to the negative pressure source of the lifting member 10.
It is gripped in the region of the end 1 a folded by and is guided into the cutout 26. The cutout portion 26 is
Belonging to the carrying wheel 21 which is arranged on the momentarily folded end 1a and is driven in the direction of rotation D. As soon as the lifted and printed product 1 is fed forward by the side 26a of the associated cutout 26 of the conveying wheel 21 and directed to the guiding gap 33, the lifting member 10 separated from the negative pressure source is treated. From the passage, it returns along the circuit 14 to the starting position for moving the printed product 1, so that the next printed product 1 is gripped and that product 1 is guided into the next cutout 26. .
Meanwhile, the printed product 1 is
Surface 28 around the front wheel portion 27 in the direction of rotation D
And into the guiding gap 33 between it and the previous printed product 1 and starts to move. Therefore, each printed product 1 is successively guided to one of the cutouts 26, and the lifting member 10 is driven synchronously with the transport wheel drive. By this method, new shingles S2 of the printed product 1 are formed, where again each printed product 1 is supported by the next printed product and further The folded end portions 1a are arranged at the lower positions, respectively. In this arrangement, the conveying wheel 21 of the moving conveyor 20 determines not only the conveying speed of the printed product 1 to be moved, as a peripheral speed, but also the spacing of the shingles. It is defined by the wheel 21 and is determined by the spacing of the wheel portions 27 (measured around the carrying wheel 21). Due to the shape of the cutout 26, the printed product 1 can be directed into the guide gap 33 without being bent or otherwise deformed. Even if the intervals between the covering tile-shaped portions are irregular in the first covering tile-shaped portion S1 and the printed product 1 may be chipped,
The device according to the invention forms a new exactly defined shroud S2 which is not irregular.

The printed product 1 leaving the moving conveyor in direction B is gripped and guided in a manner not shown before the trailing edge 1b leaves the guiding gap 33. The support and guide plates 48, 49 engage underneath the part of the printed product 1 that leaves the guide gap 33.
